How to Build a Rocket Stove Oven
If you’re looking for an efficient and eco-friendly way to cook your meals while enjoying the great outdoors, building a rocket stove oven might be the perfect solution. A rocket stove oven is a compact, portable stove that uses minimal fuel and produces very little smoke. In this article, we will guide you through the steps of building your own rocket stove oven.
Materials you will need:
– 55-gallon steel drum
– Angle grinder or metal saw
– Fire bricks
– Clay or cob mixture
– Sand
– Grate or mesh
– Insulating material (perlite or vermiculite)
– Pipe or chimney
Step 1: Prepare the drum
Using an angle grinder or metal saw, cut a large rectangular opening in the side of the steel drum, leaving a lip at the bottom to hold the fire bricks. This will serve as the combustion chamber.
Step 2: Create the combustion chamber
Place the fire bricks on the lip inside the drum, forming a rectangular shape. This will act as the base for your rocket stove oven.
Step 3: Construct the insulation layer
Mix the clay or cob with sand to create a thick, sticky mixture. Apply a layer of this mixture around the outside of the drum, covering the entire surface except for the opening. This insulation layer will help retain heat and prevent the outer surface from becoming too hot.
Step 4: Build the cooking surface
Place the grate or mesh on top of the fire bricks inside the drum. This will be the surface where you can cook your food.
Step 5: Add insulation materials
Fill the space between the drum and the insulation layer with perlite or vermiculite, which are lightweight insulation materials. This will further enhance the stove’s efficiency and prevent heat loss.
Step 6: Create a chimney
Attach a metal pipe or chimney to the opening of the drum. This will help direct the smoke away from the cooking area.
Step 7: Test and adjust
Before using your rocket stove oven, it’s essential to test its functionality. Build a small fire and observe the flame and smoke patterns. Adjust the airflow by modifying the intake vent or chimney height to achieve optimal combustion.
